PURPOSE: The aim of this investigation was to study the patient-reported outcomes of patients with microbial keratitis (MK) using the 9-item National Eye Institute-Visual Function Questionnaire (NEI VFQ-9). METHODS: Using the Sight Outcomes Research Collaborative ophthalmology electronic health record repository, patients with MK and control patients who completed the NEI VFQ-9 within 7 days of their appointment were identified. The questionnaire is scored as a mean of the 9 items on a scale from 0 to 100, with higher scores indicating better functioning...

PURPOSE: To describe the presentation and management of limbal stem cell dysfunction in ichthyosis follicularis, alopecia, and photophobia (IFAP) syndrome. METHODS: A retrospective case report. RESULTS: A 6-day-old male infant was diagnosed with IFAP syndrome based on family history and a mutation detected in the MBTPS2 gene. Initial examination showed hyperkeratotic eyelids, madarosis, and lagophthalmos, but otherwise clear corneas. He developed bilateral central corneal epithelial defects spontaneously 6 months later, which were managed with aggressive lubrication, prophylactic antibiotics, and bilateral permanent lateral tarsorrhaphies at 7 months of age...

PURPOSE: Opiorphin is an endogenous inhibitor of enkephalin-degrading enzymes. It has a strong analgesic effect in chemical and mechanical pain models. We aimed to evaluate the tear opiorphin levels in ocular pain caused by corneal foreign bodies and demonstrate whether there is any correlation with pain levels obtained from the Visual Analog Scale (VAS) score and tear opiorphin level. METHODS: Thirty-two healthy individuals and 34 individuals diagnosed with corneal foreign bodies were included in this study...

PURPOSE: To evaluate dry eye and quantitative and qualitative changes of meibomian glands with meibography in patients with pemphigus. METHODS: Twenty left eyes of 20 patients with pemphigus (group 1) and 20 left eyes of 20 age- and sex-matched healthy volunteers (group 2) were enrolled. Dry eye was evaluated with Oxford scale scoring, tear film breakup time, Schirmer 1 tests, and Ocular Surface Disease Index score assessments. Morphological changes and dropout ratio of meibomian glands were evaluated by upper and lower eyelid meibography (SL-D701; Topcon, IJssel, The Netherlands)...
